Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.

In Money Everything?
I don’t think money is everything, but we can’t do without it. Fox example, money can’t buy us happiness and a good education. And for another example, money can’t buy us good health and a long life. But we can not live without money. We need it for our daily necessities such as food,
clothes and transportation. What’s more, we need it to live a better life. In short, we
should learn the value of money and make the most of its advantages.

In many modem countries it has for some time been fashionable to think that, by free education for all-whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider" low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, We can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.
Education is ______.
A.a means
B.a purpose
C.fashionable
D.the first system
How can we get rid of garbage (垃圾) ? Do we have enough energy sources to meet our future energy needs?
These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.
For a long time, people buried garbage or dumped (倾倒) it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas, but they are chemically similar to these fossil(化石) fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source.
Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.
Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.
What two problems can man solve by burning garbage?
A.The shortage of energy and air pollution.
B.The shortage of energy and the land to hold garbage.
C.Air pollution and the shortage of fossil fuel.
D.Air pollution and the shortage of land to hold garbage.
